We carry a lot of standard type parts for many of the popular brands of x-rays.   We have been dealers for all of the brands that we support even if the manufacturer is no longer in business.  While Transworld x-ray is gone, we have sourced most of the common failure parts and have not had any problem obtaining any part to keep a system running.  We are also technically qualified to offer advice regarding repairs to Transworld, Summit or Universal brands of controls.  Contact us for advice before you scrap out a system.
